As the world’s largest manufacturer of domestic fire safety products, Kidde have been safeguarding people and property from fire and related hazards for nearly a century. For convenient fast-fit alarms, try something from their ‘Slick’ range, like this Mains-powered Optical Smoke Alarm (2SFW). It can be interconnected with up to 23 other Kidde and Firex mains alarms or used with the Optional Wireless Alarm Base (RF-SFTP) for wire-free interconnection. The 2SFW is designed for use in escape or circulation routes, as well as areas where there is a danger of cigarettes producing slow smouldering fires. The ‘Slick’ range requires installation by a professionally qualified electrician and complies with UK Building Regulations for new housing and associated standards (Grade D, BS5839, Part 6).

How it works:

Optical (or photoelectric) smoke alarms use a beam of light and a photoelectric sensor in a chamber. When there is no smoke, light passes through in a straight line. However, if smoke enters the chamber, the light beams are scattered and some will be deflected onto the sensor, triggering the alarm.
